Referring to fig. 7 to 16, the ice making pipe 3 is disposed in the case 1 and extends into the ice making compartment 13. The ice making pipe 3 is used for flowing the refrigerant, and the refrigerant in different states flows in the ice making pipe 3, so that the refrigeration or heating function of the ice making pipe 3 can be realized respectively.
At least a part of the pipeline of the ice making pipe 3, which can be in contact with the ice making housing 2, can be disposed in a spaced area between the first and second rotating members 6 and 7. Therefore, when the refrigerant in the ice making pipe 3 performs refrigeration, the ice making pipe 3 can directly absorb heat of the ice making box 2 by contacting with the ice making box 2, as shown in fig. 15, direct cooling contact ice making of the ice making box 2 is realized, and the direct cooling contact ice making is matched with air cooling refrigeration in the ice making chamber 13, so that the ice making efficiency of the ice making box 2 is improved.
Meanwhile, the portion of the piping of the ice making pipe 3 disposed between the first and second rotating members 6 and 7 can be disposed coaxially with the first and second rotating members 6 and 7. When the driving motor 4 drives the ice making box 2 to rotate through the first rotating member 6, the ice making box 2 can rotate around the part of the pipeline of the ice making pipe 3 by taking the axis of the part of the pipeline of the ice making pipe 3 as a shaft, and the contact state of the ice making box 2 and the ice making pipe 3 is maintained. Therefore, after the ice making in the ice making box 2 is completed, the driving motor 4 can control the ice making box 2 to rotate 180 degrees, so that the ice making cells 21 on the ice making box 2 are arranged downwards, and then the refrigerant in the ice making pipe 3 is used for heating, and the ice making pipe 3 is matched with the ice making box 2 to be contacted, as shown in fig. 16, the heat of the refrigerant is directly transferred to the ice making box 2, so that the ice blocks in the ice making cells 21 can be quickly dropped and stored in the ice storage box 131.
Before the ice making box 2 is turned over and de-iced, the refrigerant in the ice making pipe 3 is used for heating, so that ice at the contact part of the ice making pipe 3 and the ice making box 2 is melted, the ice making box 2 is prevented from being frozen on the ice making pipe 3, and the ice making box 2 is further ensured to be smoothly turned over.

Therefore, the drive motor 4 can rotate the ice making housing 2 about the axes of the first and second rotating shaft portions 61 and 71.
Meanwhile, the ice making pipe 3 is coaxially provided in a spaced area of the first and second rotating shaft portions 61 and 71. Therefore, when the driving motor 4 drives the ice making housing 2 to rotate, the ice making housing 2 can also rotate around the ice making pipe 3, that is, the ice making housing 2 can rotate around the axis of the ice making pipe 3, and simultaneously, the contact state of the ice making pipe 3 and the ice making housing 2 is maintained.
Referring to fig. 13 and 14, in some embodiments, the first connecting portion 62 and the second connecting portion 72 extend along the axial direction thereof, and the first connecting portion 62 and the second connecting portion 72 are coaxially arranged at intervals. Therefore, the ice making housing 2 can be stably rotated about the axes of the first and second shaft portions 61 and 71.

The relief groove 22 can provide a relief space for the ice making pipe 3 and maintain a large contact area between the ice making housing 2 and the ice making pipe 3.
In some embodiments, the ice trays 21 of the ice making housing 2 are arranged in a plurality of rows, and the relief groove 22 is formed between the two rows of ice trays 21. It should be noted that, in some other embodiments, the relief groove 22 may also be directly formed on the bottom surface of the ice making housing 2 in a concave manner.

Referring to fig. 8 to 16, in some embodiments, the ice making pipe 3 includes a shaft pipe section 31, a first supporting pipe section 32 and a second supporting pipe section 33 which are integrally bent and connected. Wherein, the shaft tube section 31 extends along the axial direction, and the shaft tube section 31 is coaxially arranged between the first rotating shaft part 61 and the second rotating shaft part 71, and the peripheral wall of the shaft tube section 31 is in contact with the bottom of the ice making box 2.

Therefore, when the ice making housing 2 is rotated to a horizontally placed state, the bottom of the ice making housing 2 can be supported on the first and second support pipe sections 32 and 33, as in the state shown in fig. 15. At this time, the refrigerant in the ice making pipe 3 is cooled, the shaft pipe section 31 and a portion of the first and second supporting pipe sections 32 and 33 can make ice in direct cooling contact with the ice making box 2, and at the same time, the first and second supporting pipe sections 32 and 33 can support the bottom of the ice making box 2, so that the ice making box 2 is stably fixed on the ice making pipe 3.
After the water in the ice making cells 21 in the ice making box 2 is completely changed into ice cubes, the ice making box 2 is controlled to be turned over by 180 degrees by the driving motor 4, the ice making cells 21 in the ice making box 2 are arranged in an orientation manner, the top of the turned ice making box 2 can abut against the first supporting pipe section 32 and the second supporting pipe section 33, the ice making cells 21 are kept in a downward state stably, and the contact state of the ice making box 2 and the shaft pipe section 31 is kept, as shown in fig. 16, at this time, the refrigerant in the ice making pipe 3 is heated, and the heat of the refrigerant is transferred to the ice making box 2 through the shaft pipe section 31 and part of the first supporting pipe section 32 and the second supporting pipe section 33, so that the ice making box 2 falls off from the ice making cells 21 stably and quickly.

The refrigerant in the ice making pipe 3 flows to the condenser 18 through the first three-way valve 19 to be cooled, and the refrigerant in the condenser 18 returns to the compressor 16 through the four-way valve 17 and the return air port 162 to be compressed again.
Referring to fig. 18, the third capillary 116 is disposed between the first three-way valve 19 and the condenser 18, one end of the third capillary 116 is connected to the first port of the first three-way valve 19, and the other end of the third capillary 116 is connected to the condenser 18. The refrigerant flowing out of the condenser 18 can be throttled and depressurized by the third capillary tube 116, and then flows to the first three-way valve 19, and further flows to the ice making pipe 3 or the evaporator 152 through the first three-way valve 19. The refrigerant flowing out of the ice making pipe 3 can be throttled and depressurized by the third capillary tube 116 and then flows to the condenser 18.
It should be noted that, in some other embodiments, the third capillary tube 116 may be replaced by a first capillary tube 112 disposed between the ice making tube 3 and the first three-way valve 19 and a second capillary tube 113 disposed between the evaporator 152 and the first three-way valve 19.
